We're been running into an issue that so far seems to be limited to our Lenovo 11e laptops and Ubuntu 17.10.
On first boot, the touchpad and keyboard will work sporadically with random keys occasionally being registered as being pressed. After some time, both the touchpad and keyboard completely stop functioning. We've replicated the issue on other 11e laptops to ensure it wasn't a hardware problem.
Touchpad and keyboard both work perfectly on Ubuntu 16.04.3
dmesg is showing a bunch of the following:
psmouse serio1: Touchpad at isa0060/serio1/input0 lost synchronization, throwing 4 bytes away.
psmouse serio1: resync failed, issuing reconnect request
psmouse serio1: synaptics: unable to initialize device
What we expect to happen:
Touchpad and Keyboard will allow user input
What happened instead:
Touchpad and Keyboard register random input or don't function at all.
